摘要: A Spanish bituminous coal was used as raw material to prepare activated carbons both by CO2 and chemical activation. The were characterized adsorption of N2 at 77 K, 273 K benzene cyclohexane 303 well mercury porosimetry helium density. microporosity the evaluated Dubinin-Astakhov equation applied isotherms α-plot method data. All studied essentially microporous. sample obtained activation with phosphoric acid had widest micropores. micropore volumes medium high determined quite similar, so adsorbates measured same type Molecular sieve effects for detected in low
